the original source code had calls to animate acid
with the blood graphic and a specific acid SFX,
which makes more sense than a zap graphic and sound.
This change makes acid look and sound distinct from
magic damage, although mechanically it's still
magic damage.
This commit only updates the XCode project for the changes.
A later commit each will update it for scons and MSVC.
A few actual changes are mixed in:
- Add a prefix header for a handful of common definitions
- Moved current_cursor into the Cursor class as a static member
- Removed the make_cursor_sword and make_cursor_watch functions
- Include tests in the All target
- Remove redundant -l flags for Common and Common-Party (since they're included in the Link phases anyway)
